San Francisco Suicide Prevention’s 24-hour Crisis Line provides immediate crisis intervention and emotional support. Since 1962, we have been answering the telephone around the clock, and have been able to maintain this service for nearly fifty years through the wonderful dedication of our volunteers. All volunteers are trained and supervised by a professional staff, and all receive ongoing training to hone their skills with the newest developments in the field of suicide prevention. The crisis line number is 415-781-0500.
